Hydrogen bonding is a weak attractive force.
O A. True
O B. False

Answers

Answer 1

Answer:

The Answer is gonna be True

Explanation : A hydrogen bond is a weak type of force that forms a special type of dipole-dipole intermolecular attraction when a hydrogen atom is bonded directly to one of the most electronegative elements like nitrogen (N), oxygen (O) or fluorine (F). This causes the hydrogen to acquire a significant amount of positive charge.

Or

Hydrogen bond is an attractive force between a partially positive charged hydrogen and a partially negative charged atom (oxygen and nitrogen). This is a very weak bond and strength of hydrogen bond (5-10 Kcal per bond) is much less than the strength of covalent bond. Hydrogen bonds are usually showed as dotted lines between two atoms.

This is the Answer for your question :3

I hope you are having a great day ❤️❤️❤️❤️❤️

Answer 2

Answer: The attraction of opposite charges between hydrogen and oxygen does not form a weak bond because oxygen-hydrogen makes hydrogen bonding. Hydrogen bonding is a very attraction force

8.A 1580 kg car is traveling with a speed of 150 m/s. What is the magnitude of the horizontal net force that is required to bring the car to a halt in a distance of 50.0 m

Answers

The magnitude of the horizontal net force required to bring the car to a halt in a distance of 50.0 m is 2370 N.

What is force?

Force is a quantity that describes the interaction between two objects or systems. It is a vector quantity, meaning it has both magnitude (size or strength) and direction. Forces can cause changes in an object's motion, shape, or internal energy.

The magnitude of the horizontal net force required to bring the car to a halt in a distance of 50.0 m can be calculated using the equation:

force = (mass * velocity^2) / (2 * distance)

where mass is the mass of the car, velocity is the initial velocity of the car, and distance is the distance over which the car is brought to a halt.

Plugging in the given values, we get:

force = (1580 kg * 150 m/s^2) / (2 * 50.0 m)

force = (237,000 N) / 100

force = 2370 N

Hence, the magnitude of the horizontal net force required to bring the car to a halt in a distance of 50.0 m is 2370 N.

What does physics mean by a work done?

In physics, the term "work" refers to the measurement of energy transfer that takes place when an item is moved over a distance by an external force, at least a portion of which is applied in the direction of the displacement.

Work done can be computed using the formula:

[tex]w=Fd[/tex]

Where:

W = work (J)

F = Force (N)

d = Distance (d)

Looking at the given, you know that you do not have a value for force, so you will have to solve for it. 

[tex]F=Ma[/tex]

Where:

F = Force

m = mass

a = acceleration

Because the object is being lifted, the acceleration will rely on gravity. Acceleration due to gravity is a constant 9.8 m/s^2. Let's list our given first:

F = ?

m = 100kg

a = 9.8m/s^2

Put that into our equation and solve:

[tex]F=mA\\F=100*9.8\\F=980Kg.m/s^{2}[/tex]

Our force is then 980 N. 

Now that we have force we can solve for Work. The given for work is as follows:

F= 980N

d = 1.4mPut that into our formula and solve:

[tex]W=Fd[/tex]

[tex]W=(980)*(1.4)\\W=1372[/tex]

Explain the differences between the properties of alpha, beta and gamma radiations.
[6 marks]

Answers

Answer:

alpha particles carry a positive charge, beta particles carry a negative charge, and gamma rays are neutral

Explanation:

Alpha rays have poor penetration power. They can cause little harm from outside. The outer layer of dead skin in humans, a thick sheet of paper, or a layer of clothes can resist alpha penetration.

However, alpha particles also have the greatest mass, which implies that they have the greatest ionizing power. If an alpha particle somehow gets into the system through inhaling or swallowing, they become the most dangerous.

Chances of alpha particles getting inside the system occur only in situations of a nuclear accident or explosion. Once inside, alpha particles can cause maximum damage to the tissues of humans and other living organisms.

Beta particles are smaller and have less tissue-damaging power when inside an organism. However, they have greater penetrative power. From the outside, beta particles can burn human skin. It would be similar to a severe sunburn.

Gamma rays have the highest penetration power. A living organism such as a human being exposed to gamma rays faces a high risk of having bone marrow and internal organs damaged.

Gamma rays can pass through a body, damaging tissue and DNA in the process. Scientists consider gamma rays to be the most dangerous form of radiation.

Also:

Alpha particles are positive, heavy, and slower in its movement in comparison to other kinds of nuclear radiation. The travel speed of alpha particles is 5-7% of the speed of light.

Radiotherapy in cancer treatment uses alpha particles to kill the cancerous cells. Because of their low penetration power, they cannot damage the healthy cells surrounding the cancerous part.

One-thousandth of the mass of a proton is the mass of a beta particle. Beta particles carry either one negative charge – an electron, or one single positive charge – a positron. Because of their small mass, beta particles can travel almost at the speed of light.

Beta particles get used as tracers for medical imaging. They also have therapeutic uses in bone and eye cancer treatment. Smoke detectors also use beta particles. Sometimes, beta particles are used for quality control. Checking the thickness of paper, for instance.

Gamma has no mass and no electrical charge. It can travel at the speed of light. There is some application of gamma rays in oncology, and for sterilizing medical instruments

Beta particles have a negative charge, alpha particles have a positive charge, and gamma rays are neutral.

What is radiation?

Energy that emanates from a source and moves through space at the speed of light is referred to as radiation. This energy has wave-like qualities and is accompanied by an electric field and a magnetic field. Radiation may also be referred to as electromagnetic waves.

Ionizing radiation and non-ionizing radiation are the two types of radiation. Non-ionizing radiation has sufficient energy to cause molecules' atoms to vibrate or move about, but not enough to deplete them of their electrons.

Gamma rays are neutral, alpha particles are positively charged, while beta particles are negatively charged.

An alpha particle is made up of two protons and two neutrons. Beta particles are thought to be highly energetic electrons. Photons are electromagnetic energy waves, and they are what gamma rays are.

Thus, this is the difference between the properties of alpha, beta and gamma radiations.

This is why exposure to X-rays on a regular basis should be avoided. Body tissues can be harmed by excessive X-ray exposure, which can also lead to cancer.

How are X-Rays created?

To create images of the body, its organs, and other internal structures for diagnostic purposes, X-rays use external radiation. A "negative" type image is created when X-rays penetrate human structures and land on specially treated plates (similar to camera film) or digital media (the more solid a structure is, the whiter it appears on the film).

Different bodily components permit various amounts of the X-ray beams to pass through when the body is exposed to X-rays.

Answers

the linear charge density of the infinite line of charge is 5 x 10^-6 C/m.

The linear charge density (λ) of an infinite line of charge is a measure of the charge per unit length. It is given by the equation:

λ = E / k. Where E is the electric field strength at a given point and k is the Coulomb's constant (9 x 10^9 N m²/C²). We know that the electric field strength at a distance of 2.0 m from the line of charge is 4.5 x 10^4 N/C. So we can substitute these values into the equation above to find the linear charge density:λ = (4.5 x 10^4 N/C) / (9 x 10^9 N m²/C²) λ = 5 x 10^-6 C/m Therefore, the linear charge density of the infinite line of charge is 5 x 10^-6 C/m. This means that there is 5 x 10^-6 Coulombs of charge per meter of length on the line of charge.

ANALOGY: Natural pressure is to artesian wells as mechanical pressure is to ___________________

Answers

Water flows naturally under pressure from an artesian well without the need for pumping.

What causes pressure in an artesian well?

A well that can bring water to the surface without a pump is known as an artesian well. This happens when the aquifer's positive pressure is high enough to force the water to the surface. This positive pressure is brought on by the confinement of an artesian aquifer between impermeable rocks or clay.

Free-flowing spring water that springs from underground wells is known as artesian water. Water in artesian wells rises to the surface naturally owing to pressure, unlike conventional wells that require a pump.

When water seeps into a porous rock material, such as limestone, sand, or gravel, artesian wells are created. Simply doing this wouldn't cause water to rise. But when a thick rock layer surrounds the porous earth.

Wells15 I stood staring, not as yet realising that this was death leaping from man to man in that little distant crowd. All I felt was that it was something very strange. An almost noiseless and blinding flash of light, and a man fell headlong and lay still; and as the unseen shaft of heat passed over them, pine trees burst into fire, and every dry furze bush became with one dull thud a mass of flames. And far away towards Knaphill I saw the flashes of trees and hedges and wooden buildings suddenly set alight.16 It was sweeping round swiftly and steadily, this flaming death, this invisible, inevitable sword of heat. I perceived it coming towards me by the flashing bushes it touched, and was too astounded and stupefied to stir. I heard the crackle of fire in the sand pits and the sudden squeal of a horse that was as suddenly stilled. Then it was as if an invisible yet intensely heated finger were drawn through the heather between me and the Martians, and all along a curving line beyond the sand pits the dark ground smoked and crackled. Something fell with a crash far away to the left where the road from Woking station opens out on the common. Forthwith the hissing and humming ceased, and the black, domelike object sank slowly out of sight into the pit.17 All this had happened with such swiftness that I had stood motionless, dum bfounded and dazzled by the flashes of light. Had that death swept through a full circle, it must inevitably have slain me in my surprise. But it passed and spared me, and left the night about me suddenly dark and unfamiliar.The narrators attitude in paragraph 15 is best described as Answer choices for the above questionA. hostile.B. enthusiastic.C. observant.D. sarcastic.The authors word choice in paragraph 16 helps build a suspenseful tone by emphasizing that Answer choices for the above questionA. the narrator cannot see what is happening.B. there is no way to escape from the attack.C. the Martians have suddenly come into view.D. many people were hurt or killed.Based on the narrators attitude in the final paragraph, the tone shifts to Answer choices for the above questionA. shocked.B. bitter.C. peaceful.D. mysterious.
